To all zulzonm'tmay. czmcerm,

Be it;knownt,l1at I,Enwnnn 1V. NIMMER, a citizen of the United StateS residing; at Milwaukee, inthc county otMilwaukee "and State of \Visconsin, hayge' inventedf certain new and useful linl'n'ovelnents in a' Syringe, of which the :t'ollowing s a speclhcation.

Thisinvention relatesto asyringe and has i for its principal object to generally improve upon syrlnges by providing a device of this nature which will be extremely simple, du

rable and inexpensive in construction, one which iseflieient and reliable in operatlon, and Well adapted to the purpose for which 1t it designed. r

W iththe above and numerous other objects in View, the invention resides in certain novel features of construction, and the combination and arrangement of parts as will be hereinafter fully described.

In the drawing I Figure 1 is an elevational- View of the Figure2 is a front elevation of the device, Figure 3 is an elevationalview of the device with the outer sleeve removed, Q

Figure 4 is a transverse sectionalfview of Figure 5 is an elevational view of the device with the outer sleeve removed show-' ing the various parts separated.

Figure 6 is a longitudinal section through the device in a contracted position,

Figure 7 the device in an extended position.

Figure 8 is a sectiontaken on the line 88 of Figure 6 looking inthe direction of the arrows, and i 7 i I Figure 9 is a section taken on the line 9 the arrow.

Referring to the drawing in detail it will be seen that 1 designates the body member of the device which is provided with an annular' recess for receiving any. suitable bulb 2. 1A sleeve 3 extends fromthe body memher 1 and is provided upon its periphery with the spiral groove 4, and the bayonet slot. 5. r The nozzle of the device consists of the tube 6 provided with a plurality of opening's 7 arranged in series extending transversely therethrough and the forward end of the tube 6 is also open. In the forward.

end there is situated a plug 8 having a cen tral opening and a conical seat 9.: Onthe rear end, of the tube a pin 10 1s situated and is a longitudinal section through 9 of Figure 7 looking in the direction of isadaptedrtofit. in the slot 5' for-- holding the tube 6, in lockedg.engagement with the sle ve j I a A sleeve 11, is., slidably. mounted on the tube 6, and. is. provided with, a plurality of openings lZ'arranged in series. The forward end of the sleeve is closed and provided with a central opening in which is situated a plug 13 having its rear end pointed so as to fit in the seat 9 of the plug 8 provided inthe tube 6 and thus act as a valve. A plurality of spirally formed grooves 14 are arranged in the plug 13 around the center thereof so that liquid passing therethrough will be deliveredforwardly of the nozzle mechanism in a whirl. The rear end of the sleeve 11 is slightly enlarged as is shown at 15 so as to fit over the sleeve 3 of the bodymember 1 and a reinforcing collar 16 is arranged on the rear portion of the enlarged portion 15. A pin 18 passes through the collar 16 and enlarged portion 15 so as to engage the. spiral groove 4 and thus it will be seen that by rotating the sleeve 11 in a counter-clockwise direction this sleeve will be moved forwardly on the tube 6. WVhen the sleeve 11 is moved forwardly on the tube 6 liquid may pass through the forward end of the nozzle by passing through the aperture in the plug 8 and through the spiral grooves 14in the plug 13. When the From the foregoing description,taken. in 7 connection with the accompanying drawings, the constructlon and operation of the device will be readily understood without a more'extended explanation. As numerous changes. in form, proportion,- and in the sorted to without departing from the spirit of this invention, I do not wish to be limited to the construction herein shown and described other than as claimed.

Having thus described my inventionwhat I claim as new is lpA'device' of the class described comprising a body member,a tuberextending therefrom, a sleeve slidable on the tube,

minor details of construction may be remeans provided for sliding the sleeve on the tube, said sleeve and said tube provided with transverse openings adapted to register when the sleeve is in a contracted position and provided with end apertures, and means provided in the ends of the tube and sleeve for preventing liquid from passing therethrough when the device is in a contracted position.

2. A device of the class described com prising a body member, a tube attached thereto, a sleeve slidable on the tube, means for sliding the sleeve longitudinally on the tube, said sleeve and said tube provided with end openings, a plug situated in the forward opening in the tube and provided with an aperture, and a plug situated in the opening of the sleeve and having openings arranged eccentrically therein, said second plug adapted to close the opening in the first mentioned plug when the sleeve is in a contracted position upon the tube.

In testimony whereof I ailix my signa ture in presence of two Witnesses.
